SPECIFICATION forming part of Letters Patent No. 372,828, dated November 8, 1887.

I Application filed February 18, 1887. Serial No. 228,015. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE VAN WAGENEN, of the city and county of New York, in the State of New York, have invented a new and useful Improvement in Stoves for Heating Cars and Boats or Vessels, of which the following is a specification. 1

The object of my invention is to provide a stove which has its exterior so protected and which is so inclosed that in case of the stove being overturned or crushed the fire cannot escape from confinement, nor can the exterior of the stove become heated to a red heat.

In carrying out my invention I surround the stove proper by a jacket or shield, which is of wrought metal, and which is preferably double or composed of two parallel walls, at:

fording an air-space between the stove and the inner wall of the jacket and between the two walls of the jacket. The doors of the stove and in the jacket-walls may slide horizontally, and I provide a curved latch or hook which is pivoted to the door and engages a locking projection on the casing or part which is closed by the door, and which is of such construction that in any position of the stove, save that in which the door will gravitate to closed position, the latch or hook will remain engaged with the lock or projection to hold thedoor closed. The invention consists in novel combinations of parts particularly hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figurel is a vertical section of a stove embodying my invention, and having a tubular jacket or shield with double air-spaces which entirelyv incloses the stove. Fig. 2 is a horizontal section of the stove upon the plane indicated by the dotted line-w m, Fig. 1. Fig. 3 is a plan of a rectangular tubular brace or distance piece, which is employed to maintain the top plates of the double jacket at the required distance apart, and in which is the smoke-outlet, protected by a grating. Fig. 4 is a front elevation, on a larger scale, of a portion of the upright wallof the stove or one off'its jackets, having a horizontally-sliding door, which is locked in closed position by a latch or hook embodying my invention; and Fig. 5 is aview over the two airspaces d d.

similar to Fig. 4., showing the position ofsuch parts when the stove is overturned, and illustrating how the curved latch or hook,even in that position, holds the door closed.

Similar letters of reference designate corresponding parts in all the figures.

A designates the fire-pot of the stove or the stove proper, which may be of cast-iron, and

which has in it a grate, B, of any ordinary construction, below which is an ash-pan, B. The top of the castmetal shell forming the stove is closed by a plate, A, which may be secured thereto by bolts or otherwise, and in this top is a smoke-outlet, C, which is protected by a grating, 0.

I have here represented the stove A as surrounded by a double jacket or shield, which is composed of bottom plates, D D, upright walls D D and top plates, D D Between the double walls of the jacket or shield and between the inner wall and the stove proper, A, there are formed air-spaces d d. The stovebody A can never come in contact with the inner wall, D of the double jacket or shield, nor can the inner and outer walls, D D", of such double jacket or shield come in contact, because of pins, braces, projections, or distance-pieces, (1 which extend across or bridge These projections, braces, or distance-pieces may consist of pins riveted fast in the upright walls D D of the double jacket, those in the outer wall, D, bearing at their inner ends against the inner wall, D and those on the inner wall bearing against the stove A. The top plate, D,of the double bottom has similar pins or projections, d riveted to it and on the ends of which the bottom of the stove A is supported, and

between the bottom plates, D D, are distancepieces 01*, which may consist of thimbles or sleeves surrounding rivets (P, by which the two bottom plates, D D, are secured permanently together. The double jacket or shield is made either of wrought metal- -such as'thick sheetiron or thin iron plate,-and in order to facilitate the replacement of the stove A when burned out, I may make the two cylindric upright walls, D D in semicircular or cylindric sections, as shown in Fig. 2, or in sections of other form united by vertical and separable joints (1. I have here shown these joints as 1 formed by riveting angle-irons d to the sections of the upright walls D D, and bolts (1 inserted through the outwardly-extending radial flanges of such angle-irons. Even if the stove be overturned and crushed the fire cannot escape from the stove proper, A, and in case thejacket orshield is crushed or flattened, and even ifthestove proper be broken, the pins, braces, or distance-pieces (1 will prevent the walls of the stove from making contact with the inner wall, D, of the jacket or shield and will prevent contact of the walls D I) of the jacket or shield with each other.

At the top of the stove I have represented tubular distance pieces or braces D, which may be rectangular in their horizontal plan View, as shown in Fig. 3, and flanged at top and bottom. The tubular distance-pieces or braces I) surround and have formed within them smoke-outlets O, which are continuous and coincident in both the stove A and the double top plates, D D, and in each case these openings 0 are protected by gratings c, and at the top is a nipple or projection, O, with which the smoke-pipe may be connected. Even if this nipple or projection 0 becomes knocked off and the smoke-pipe detached and the stove overturned, the [ire cannot escape because of the strong bar-gratings c, which protect the smoke-outletin the several plates forming the top of the stove and top of the jacket or shield.

Above the gratings c, I have shown scrapers or cleaners c, with which are connected handles 0, extending to the exterior of the jacket or shield, and by these scrapers or cleaners the gratings 0 can be kept free from dust and dirt. The scrapers or cleaners c are by their handles 0 reciprocaled across the gratings c in a direction transverse to the length of the bars and spaces in such gratings.

As before described, the bottom plates, D D, are securely riveted together and the up right walls D D are connected therewith by separable joints (1.

The tubular distance pieces or flanged braces D may have their lower flanges permanently secured by riveted joints (1 respectively to the stove top plate,A,and the lower top plate, D of the jacket or shield, and their upper flanges may be secured by separable joints (1", formed by bolts or screws to the top plates, D D

I have here represented the stove or heater as designed for heating waterto produce a circulation of hot water through the radiating pipes in the car or other locality, and in the stove is a coil, E, for water-circulation, and which, by the inlet-pipe e and the outlet-pipe 6, may be connected with the radiator system.

In cases where it is simply desired to heat air the water-coil E orheater may be removed, and through holesfiu the bottom plates, D D, and in the top plates, D D", a circulation of air upward through the air-spacesd d may be maintained and the air heated by contact with the stove and innerjacket walls. The walls D D of the jacket may also be perforated at f.

The stove A and the upright jacket-walls D D have coincident doors F, which are fitted to the horizontal slideways f upon the upright walls of the stove and jacket, and corresponding ash-pit doors H, which are fitted to horizontal slideways it. These doors will be arc-shaped, as shown in Fig. 2, soas ttrform a circular section of the stove and jacket, and in Figs. 4 and 5 I have represented a very secure fastening which may be employed for each of the doors. The door represented in Figs. 4 and 5 is supposed to be one of the fire-doors F, fitted to the slideway f upon the stove-body A, or in a like manner fitted upon either of the walls D D of the jacket or shield. It will be understood that the same construction also applies to the ashpit doors H. I have represented by the arrows .9 in Figs. 4 and 5 the direction in which the door F must move to open, and I have represented as pivoted to the door at i a curved hook or latch, I, which is of peculiar construction and has a shoulder or beak, t", engaging a projectiomi upon the stove-easing A. The latch or hook I may swing in a loop or keeper, J, secured to the door F. The latch or hook I is bowed or curved inward and downward relatively to the sliding door F from its pivot i to its shoulder i, which ongages the projection i. This latch or hook I is so formed that gravity will, in all positions of the stove which would cause the door to slide open by gravity, hold the latch or hook in secure engagement with its locking projection i and in all those positions of the stove wherein the hook or latch I will fall away from the projection i gravity will cause the door F to keep closed against the stop 11". For example, when the stove is overturned or thrown upside down, with its vertical axis at an inclination, in which position the door is represented in Fig. 5, the gravity of the latch or hook which is exerted on the line of the arrow 8 still holds the said latch or hook in engagement with its locking projection i". I have shown applied to the door F a damper, f which has a sliding movement in guides or ways f and which is provided with slots f which may by its movement be brought into and out of coincidence with corresponding slots f in the door. The ash-pit doors H will usually be provided with such dampers, and the fire-doors F may, if desired, also be provided with similar dampers, as shown in Figs. 4 and 5.

In order to prevent the latch or hook Ifrom being kicked upward or accidentally disengaged from its projection 5 I have represented a guard, I, as secured to the door F below the hook or latch I, and shielding or protecting the lower edge of the latter, so that contact cannot be made with it.

The grating or guard c, composed of metal bars or rods arranged parallel and having narrow spaces between them, is preferable to a guard or shield of wire-gauze or perforated sheet metal, because not so likely to clog with wet soot and dirt, and this is particularly true when there is used a scraper or cleaner 0, which tends to jar the bars of the grating and prevent the accumulation of soot and dirt.

WhatI claim as my invention, and desire to secure by Letters Patent, is-

1. The cornbination,with astove,of a double jacket or shield, forming two air-spaces completelyinclosing the stove at the bottom, sides, and top, and having pins or projections secured at one end inthe double jacket or shield and extending across both air-spaces, to prevent contact of the stove with the inner jacket-wall and contact of the j acket-walls with each other, substantially as herein described.

2. The combination, with a stove, of ajacket inclosing the stove and provided with pins, braces, or projections bearing against the stove, and composed of an upright cylindric wall made in separable sections secured together by vertical joints, and top and bottom plates to which the sections of the upright wall are secured, substantially as herein described.

3. The combination,with astove and ajack et or shield completely inclosing the stove, each having at the top a SIllOkGOlllJlGi] protected by a grating composed of parallel bars and intervening spaces, of a cleaner or scraper for each outlet'and having a handle accessible from outside the jacket or shield for reciprocating the scraper or cleaner in a direction transverse to the length of the bars and spaces, substantially as herein described.

4. The combination, with the stove, of a double jacket or shield inclosing the stove and composed of the bottom plates, D D, the upv right walls D D both being maintained out of contact with each other and with the stove, and the upright walls having fire and ash-pit doors coinciding with those of the stove and the top plates, D D, with the interposed flanged distance-pieces or tubular braces D through which is the smoke-outlet, substantially as herein described.

5. The combination of the inner stove and a double jacket or shield entirely inclosing it and consisting of the two bottom plates, D D, riveted togetherfand having interposed between them and between the upper plate, D, and the stovebottom braces or projections, the upright walls D D each composed of separable sections united by vertical joints and detachably secured to the bottom plates, D D, and the top plates, D D detachably secured to the upright walls, and the tubular flanged distance -pieces or braces D each permanently riveted at its lower flange to a plate and having its upper flange detachably bolted to the plate above, substantially as herein described.

6. The combination, with a stove and a double jacket or shield completely inclosing the stove and having at the top a smoke-outlet through the stove and double top of the jacket or shield, the smoke-outlet in each of the top plates of the stove and double jacket being protected by a grating, of tubular braces interposed between the jacket-walls and between the stove and the innerjacket-wall, and serving to hold said walls or top plates at proper distances apart and surrounding the grated smoke outlets, substantially as herein described.

7. The combination, with the stove and the horizontally-sliding door, of the curved latch or hook I, lying against the face of the door and pivoted at one end to the door, and the projection t upon the outside of the casing, with which the latch engages, substantially as herein described.

8. The combination, with a stove and a horizontally-sliding door, of the curved latch or hook I, pivoted at one end to the door and hooked at the other end, a projection, V, on the casing, with which the latch engages, and

a guard, I, secured to the door beneath the 0
